Description

Technical Field

[0001] This invention relates to the field of door and window conveying technology, specifically to an automatic sorting and conveying device and sorting method for door and window processing. Background Technology

[0002] Window and door profiles are core components in the manufacturing of building windows and doors. They are usually made of materials such as aluminum alloy, thermally broken aluminum, PVC plastic, or aluminum-clad wood through extrusion molding. They have various cross-sectional shapes, including rectangular, T-shaped, L-shaped, and I-shaped profiles. The length of the profiles is generally between 3 and 6 meters, which are typical long strip materials. On the window and door processing production line, the profiles need to go through multiple conveying and transfer processes from extrusion, cutting, surface treatment to final assembly. The sorting and conveying link is the key link between processing and assembly. Its conveying efficiency, detection accuracy and process integration directly affect the production capacity and finished product quality of the entire production line.

[0003] When door and window profiles travel along the conveyor line, existing technologies mostly rely on single visual inspection. Door and window profiles have complex cross-sectional shapes and often have curved grooves or decorative textures on their surfaces. Furthermore, the profiles may vibrate or sway slightly during transport. A single inspection method is difficult to achieve comprehensive coverage of various defects under dynamic transport conditions, which can easily lead to missed detections or misjudgments, affecting the accuracy of subsequent sorting. Moreover, existing technologies cannot perform differentiated sorting and transport of profiles, so some improvements are needed. Summary of the Invention

The two sets of pneumatic telescopic rods are connected to the workshop air supply pipeline. The two sets of grippers are detachably installed at one end of the two sets of pneumatic telescopic rods. The structures of the two sets of grippers are the same, and the oil supply pipeline is built into the inside of the two sets of grippers.

[0008] The present invention further describes that the fixing plate is fixedly installed inside one end of the gripper, one end of the spring is connected to the fixing plate, the coated sponge block is embedded inside the gripper, one end of the coated sponge block is connected to the other end of the spring, the other end of the coated sponge block extends to the outside of the gripper, and the side of the coated sponge block connected to the spring is a flexible sealing block.

[0009] The present invention further illustrates that the two sets of conveying coating balls are installed at intervals inside the other end of the gripper, and the two sets of oil storage tanks are symmetrically installed at both ends of the outer side of the third conveying detection frame. The positions of the two sets of oil storage tanks correspond to the positions of the two sets of grippers, and the two sets of oil storage tanks are connected to the two sets of grippers through hoses.

[0010] The present invention further illustrates that the fourth conveying detection frame is fixedly installed at one end of the movable conveying seat, and the structure of the fourth conveying detection frame is the same as that of the third conveying detection frame; The second sorting robot is placed on the floor of the production workshop, located on one side of the second conveyor line.

[0011] The present invention further illustrates that a conveying control system is provided in the first conveying line. The conveying control system includes a data acquisition module and a control module. The data acquisition module and the control module are connected by a signal. The data acquisition module includes an image recognition submodule, a laser recognition submodule, and an analysis submodule. The image recognition submodule is electrically connected to the first conveying camera and the second conveying camera.

The sorting control submodule is electrically connected to the first sorting robot and the second sorting robot.

[0013] Includes the following steps: Step 1: When sorting and conveying are required, staff use a transport device to place the door and window profiles sequentially on the first conveyor line; Step 2: Start the first and second sorting and conveying components to sort and convey the door and window profiles. Step 3: After the sorting and conveying operation is completed, the door and window profiles are sorted and conveyed a second time. Step 4: After the secondary sorting and conveying is completed, the conveying control system performs the conveying and coating operation on the door and window profiles at the front end of the second conveying line.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The present invention achieves comprehensive coverage detection of three-dimensional defects such as pits and protrusions on the surface of door and window profiles, as well as planar defects such as scratches and coating blistering during the conveying process, which significantly improves the comprehensiveness and accuracy of defect identification. At the same time, it performs differentiated sorting according to defect type. Defect-free qualified products are picked up by the first sorting robot and transferred to the second conveyor line for continued circulation. Repairable parts with slight scratches on the surface are transported along the original conveyor line to the subsequent rework production line. Defective products are rejected and placed on the sorting rack for centralized waste collection. While ensuring the normal conveying of qualified products, the present invention achieves accurate interception of defective products and maximizes the utilization of repairable parts. In addition, the laser displacement sensor can monitor the lateral offset of the profiles in real time during the conveying process and control the return operation. This not only ensures that the profiles are always in the optimal detection area to ensure the accuracy of defect detection, but also effectively avoids collision damage between offset door and window profiles and the detection frame. By setting up an independent secondary sorting and conveying link during the conveying process, the third and fourth conveying detection frames on the mobile conveyor seat are used to conduct secondary defect re-inspection of repairable door and window profiles under static conditions. This effectively avoids misjudgment of minor scratches caused by conveying vibration or obstruction during the initial dynamic inspection, significantly improves the reliability of repairable part judgment, ensures that defective products are not mistakenly placed downstream, maximizes the recycling of repairable parts, reduces unnecessary material scrapping, and balances strict quality control with production economy. By combining the clamping and handling of door and window profiles with the application of rust-preventive oil, the rust prevention treatment is completed simultaneously during normal transport, eliminating the need for a separate offline oiling station. This significantly improves the integration and production efficiency of the door and window processing line. At the same time, the use of a rolling coating method effectively avoids scratches on the surface coating of the profiles during the coating process. Furthermore, the flexible floating structure can adapt to the slight undulations on the surface of the profiles, ensuring a continuous and uniform oil film. Excess rust-preventive oil is returned to the coating sponge block for temporary storage, preventing oil drips from contaminating the transport line. Attached Figure Description

The two sets of first laser displacement sensors 213 are symmetrically installed at both ends of the first conveying detection frame 21 to assist in detecting whether the door and window profiles 11 are deviated during the conveying process. The first conveying camera 214 is fixedly installed on one side of the first conveying detection frame 21 to assist in identifying the position and size of the door and window profiles 11. The second conveying detection frame 22 is detachably installed on the other end of the first conveying line 1, located on one side of the first conveying detection frame 21, to assist in sorting and conveying detection operations. The structure of the second conveying detection frame 22 is the same as that of the first conveying detection frame 21. The first sorting robot 23 is placed on the floor of the production workshop, located on one side of the first conveyor line 1, and is used to cooperate in sorting and conveying operations. The second conveyor line 3 is also placed on the production workshop floor, located on one side of the first conveyor line 1, and is used to cooperate in sorting and conveying operations. Two sets of first electric slide rails 31 are fixedly installed at both ends of the second conveyor line 3 to cooperate in conveying operations. The second conveyor line 3 is also equipped with a second sorting and conveying assembly 4. The second sorting and conveying assembly 4 includes a mobile conveyor seat 41, two sets of second electric slide rails 411, a third conveying detection frame 42, a second laser contour detector 421, a second conveying camera 422, two sets of pneumatic telescopic rods 423, two sets of grippers 424, coated sponge blocks 425, two sets of conveying coated balls 426, two sets of oil storage tanks 427, a fixing plate 428, a spring 429, a fourth conveying detection frame 43, and a second sorting robot 44. The mobile conveyor seat 41 is slidably mounted on two sets of first electric slide rails 31, and two sets of second electric slide rails 411 are symmetrically mounted on the outer sides of the mobile conveyor seat 41 for cooperating in conveying operations. The third conveying detection frame 42 is slidably mounted on two sets of second electric slide rails 411 to cooperate in conveying coating operations. The second laser contour detector 421 is detachably mounted on the top inside of the third conveying detection frame 42 to cooperate in performing secondary detection operations on the door and window profile 11. The second conveying camera 422 is fixedly mounted on the outside side of the third conveying detection frame 42 to cooperate in identifying the position and size of the door and window profile 11. Two sets of pneumatic telescopic rods 423 are symmetrically installed on both sides of the inner wall of the third conveying and testing frame 42. The two sets of pneumatic telescopic rods 423 are connected to the workshop air supply pipeline (not shown in the figure). Two sets of grippers 424 are detachably installed at one end of the two sets of pneumatic telescopic rods 423 to cooperate in conveying and clamping the door and window profiles 11. The structures of the two sets of grippers 424 are the same, and the internal oil supply pipelines of the two sets of grippers 424 are built in. A fixing plate 428 is fixedly installed inside one end of the gripper 424 for installation and fixing operations. One end of the spring 429 is connected to the fixing plate 428. A coated sponge block 425 is embedded inside the gripper 424. One end of the coated sponge block 425 is connected to the other end of the spring 429. The other end of the coated sponge block 425 extends to the outside of the gripper 424. The side of the coated sponge block 425 connected to the spring 429 is a flexible sealing block to prevent rust-preventive oil from seeping out when not clamped. Two sets of conveying coating balls 426 are spaced apart and installed at the other end of the inside of the gripper 424 to cooperate in conveying coating operations on the door and window profiles 11. Two sets of oil storage tanks 427 are symmetrically installed at both ends of the outside of the third conveying and detection frame 42. The positions of the two sets of oil storage tanks 427 correspond to the positions of the two sets of grippers 424. The two sets of oil storage tanks 427 are connected to the two sets of grippers 424 through hoses. The hoses connecting the two sets of oil storage tanks 427 and the two sets of grippers 424 are covered with flexible drag chain sleeves (not shown in the figure) to prevent hose tangling and leakage due to bending. The fourth conveying detection frame 43 is fixedly installed at one end of the movable conveying seat 41. The structure of the fourth conveying detection frame 43 is the same as that of the third conveying detection frame 42. The second sorting robot 44 is placed on the floor of the production workshop, located on one side of the second conveyor line 3, and is used to assist in sorting and conveying operations. The first conveyor line 1 is connected to the subsequent production line in the workshop (not shown in the figure); The first conveyor line 1 is equipped with a conveying control system, which includes a data acquisition module and a control module. The data acquisition module and the control module are connected by a signal. The data acquisition module includes an image recognition submodule, a laser recognition submodule and an analysis submodule. The image recognition submodule is electrically connected to the first conveyor camera 214 and the second conveyor camera 422. The laser recognition submodule is electrically connected to the first laser contour detector 212, the laser displacement sensor 213 and the second laser contour detector 421. The control module includes a conveying control submodule and a sorting control submodule. The conveying control submodule is electrically connected to the first conveyor line 1, the second conveyor line 3, the first electric slide rail 31, and the second electric slide rail 411. The sorting control submodule is electrically connected to the first sorting robot 23 and the second sorting robot 44.

[0019] The conveying control system includes the following specific operating steps: Step 1: When sorting and conveying are required, the staff uses the transport device to place the door and window profiles 11 sequentially on the first conveyor line 1.

[0020] Step 2: Start the operation of the first sorting and conveying component 2 and the second sorting and conveying component 4 to sort and convey the door and window profiles 11; Specifically, the conveying control system starts the first conveyor line 1 through the conveying control submodule. The first conveyor line 1 conveys the door and window profile 11 backward to the first conveying detection frame 21 and the second conveying detection frame 22 for dual detection. During the backward conveying of the door and window profile 11 along the first conveyor line 1, the conveying control system controls the first laser contour detector 212 through the laser recognition submodule to acquire the three-dimensional contour data of the surface of the door and window profile 11, and controls the first conveying camera 214 through the image recognition submodule to collect the two-dimensional image information of the surface of the door and window profile 11. The system uses data fusion to comprehensively judge surface defects. The three-dimensional contour data is mainly used to identify pits, protrusions, and deeper scratches exceeding a set threshold. The two-dimensional image... The information is mainly used to identify planar and microscopic defects such as shallow scratches, coating blistering, and color difference. The detection results of the two are cross-checked to improve the comprehensiveness and accuracy of defect identification. The internal configuration of the second conveying detection frame 22 is the same as that of the first conveying detection frame 21. When the door and window profile 11 arrives at the second conveying detection frame 22, the control system executes the above detection process again and compares the results of the two detections. If the two detection conclusions are consistent, the subsequent sorting operation is prepared. If the two conclusions are contradictory, the control system marks the door and window profile 11 as a piece to be confirmed and does not perform the sorting operation for the time being. An error message is sent to the staff for subsequent manual review to avoid misjudgment caused by accidental error in a single detection.

[0021] If the conveying control system detects that the door and window profile 11 is a qualified product with no surface defects, the conveying control system controls the first sorting robot 23 through the sorting control submodule to clamp the door and window profile 11 and place it at the front end of the second conveyor line 3 to wait for subsequent operations. If the conveying control system detects that the surface of the door and window profile 11 has slight scratches, the conveying control system determines that the door and window profile 11 is a repairable part. The conveying control system controls the first sorting robot 23 to clamp the door and window profile 11 and place it at the rear end of the second conveyor line 3. The door and window profile 11 is then conveyed along the first conveyor line 1 to the subsequent production line in the factory to wait for the workers to collect it. If the conveying control system detects that the surface of the door and window profile 11 has damage, the conveying control system determines that the door and window profile 11 is a defective product. The conveying control system controls the first sorting robot 23 through the sorting control submodule to clamp the door and window profile 11 and place it on the sorting rack 12 for waste collection.

[0022] Furthermore, during the above operations, the conveying control system controls two sets of laser displacement sensors 213 through the laser recognition submodule to detect the position status of the door and window profile 11 during the conveying process and analyzes it through the analysis submodule. If the conveying control system detects that the two sets of laser displacement sensors 213 have received signals, the conveying control system determines that the door and window profile 11 has deviated during the conveying detection process. The conveying control system first controls the first conveying line 1 to stop, and then uses the first conveying camera 214 to detect the position status of the door and window profile 11 and controls the first sorting robot 23 to clamp and adjust the door and window profile 11, so that the conveying status of the door and window profile 11 is corrected, so as to avoid affecting the accuracy of the defect detection operation. At the same time, it can prevent the door and window profile 11 from damaging the first conveying detection frame 21 and the second conveying detection frame 22 during the conveying process.

[0023] Through the above steps, by utilizing the complementary fusion of laser contour 3D data and 2D image information, comprehensive detection of three-dimensional and planar defects on the surface of door and window profiles is achieved. The dual detection and cross-verification of results using the first and second detection frames significantly reduces the risk of misjudgment in a single detection, greatly improving the comprehensiveness and accuracy of defect identification. Simultaneously, differentiated sorting based on defect type and precise sorting of qualified, repairable, and defective products based on comprehensive judgment results ensures the normal transport of qualified products while effectively intercepting defective products and maximizing the utilization of repairable parts. Furthermore, the laser displacement sensor can monitor the lateral offset of the profiles during transport in real time and control the return operation, ensuring that the profiles are always within the optimal detection area to guarantee the accuracy of defect detection, and effectively preventing collisions and damage between offset door and window profiles and the detection frame.

[0024] It should be noted that the first and second conveyor lines are existing technologies and will not be discussed in detail here.

[0025] Step 3: After the sorting and conveying operation is completed, the door and window profiles 11 are sorted and conveyed a second time. Specifically, after completing the above steps, the conveying control system controls the second sorting robot 44 through the sorting control submodule to perform a secondary sorting and conveying operation on the repairable door and window profiles 11. The conveying control system first controls the second sorting robot 44 through the sorting control submodule to clamp the door and window profiles 11 and place them separately at the rear end of the second conveying line 3, waiting for secondary inspection. Then, it controls the first electric slide rail 31 to start, and performs a secondary defect re-inspection operation on the repairable door and window profiles 11 in a stationary state through the third conveying inspection frame 42 and the fourth conveying inspection frame 43 on the moving conveying seat 41. If the scratches on the surface of the door and window profiles 11 are no longer visible or extremely slight after the secondary inspection, and meet the qualified product standard, the control system marks them as qualified products and keeps them at the rear end of the second conveying line 3 or in a nearby position to prepare for the next step of operation.

[0026] If the secondary inspection determines that there are still unacceptable obvious scratches or other defects on the surface of the door and window profile 11, the control system marks it as an unrepairable defective product and controls the second sorting robot 44 to clamp and transfer it to the sorting rack 12 and send the defective product information to the staff, who then take out the defective product.

[0027] Through the above steps, an independent secondary sorting and conveying link is set up in the conveying process, which limits the flow path of repairable parts to the controllable area at the rear end of the second conveyor line 3. Through the direct handover by the first sorting robot 23, the process interruption caused by the profiles flowing to unreachable subsequent production lines is avoided. The third and fourth conveying detection frames on the moving conveyor seat are used to conduct secondary defect re-inspection of repairable door and window profiles under static conditions, which effectively avoids the misjudgment of slight scratches caused by conveying vibration or obstruction in the initial dynamic inspection, significantly improves the reliability of repairable part judgment, ensures that defective products are not mistakenly put downstream, maximizes the recycling of repairable parts, reduces unnecessary material scrap, and takes into account both strict quality control and production economy.

[0028] Step 4: After the secondary sorting and conveying is completed, the conveying control system performs the conveying and coating operation on the door and window profiles 11 at the front end of the second conveying line 3; Specifically, the conveying control system first performs graded coating operations based on the position and state of the profile to be coated. The conveying control system sets the priority of the coating operation to the end first and then the front, that is, it prioritizes the repairable parts located at the end. The control system detects whether there are repairable parts at the end of the second conveying line 3 through the second conveying camera 422. If there are repairable parts, the coating operation is performed on them first. If there are no repairable parts at the end, the coating operation is performed on the defect-free qualified products at the front.

[0029] Furthermore, after determining the coating target, the conveying control system first controls the first electric slide rail 31 and the second electric slide rail 411 to start, and accurately positions the moving conveying seat 41 and the third conveying detection frame 42 and the fourth conveying detection frame 43 on it directly above the target door and window profile 11, so that the two detection frames correspond to the two end areas of the profile respectively. Then, the control system controls the two sets of pneumatic telescopic rods 423 to extend outward synchronously, driving the two sets of grippers 424 to move towards each other, pressing the two sides of the door and window profile 11 from above.

[0030] It should be clarified that in this step, the function of the gripper 424 is to stably press the door and window profile 11 onto the conveying surface of the second conveyor line 3, and not to lift the door and window profile 11 upwards, so that the door and window profile 11 remains stationary in the subsequent process.

[0031] Furthermore, during the closing and clamping process of the gripper 424, one side of the coated sponge block 425 first flexibly contacts the profile surface, the spring 429 is compressed and contracts, triggering the oil supply line to open, and the oil storage tank 427 supplies a small amount of rust-preventive oil to the coated sponge block 425 through the hose and the built-in oil supply line to perform static pre-oiling on the clamping area. After the gripper 424 is fully clamped, the conveying coating ball 426 forms a tight rolling contact with the surface of the door and window profile 11 under the flexible floating action provided by the spring 429. At this time, the door and window profile 11 remains stationary relative to the second conveying line 3 under the clamping pressure, while the control system drives the second electric slide rail 411 to drive the third conveying detection frame 42, the pneumatic telescopic rod 423 and the gripper 424 to move back and forth along the length direction of the door and window profile 11. During the movement of the gripper assembly relative to the stationary profile, the conveying coating ball 426 rolls purely on the surface of the door and window profile 11, uniformly coating the rust-preventive oil on the profile surface and the area around the clamping point.

[0032] Furthermore, after coating is completed, if the coated object is a defect-free qualified product, the control system increases the clamping force of the gripper 424 to lift the door and window profile 11 from the front end of the second conveyor line 3, and moves it along the first electric slide rail 31 via the movable conveyor seat 41 to the end of the second conveyor line 3 for temporary storage, waiting for the second sorting robot 44 to collect it. If the coated object is a repairable part, it is already at the end and will directly wait for collection after coating. After completing one coating, the movable conveyor seat 41 returns to the standby position to prepare for the next cycle operation.

[0033] Through the above steps, the clamping and handling of door and window profiles and the application of rust-preventive oil are combined into one process. Rust prevention is completed simultaneously during normal transport, eliminating the need for a separate offline oiling station. This significantly improves the integration and production efficiency of the door and window processing line and resolves operational conflicts when multiple objects coexist. The use of a rolling coating method ensures a real and effective relative rolling between the conveying coating rollers and the surface of the door and window profiles, effectively preventing scratches on the surface coating during the coating process. Furthermore, the flexible floating structure can adapt to the slight undulations of the profile surface, ensuring continuous and uniform oil film application. Excess rust-preventive oil is temporarily stored in the coating sponge block, preventing oil drips from contaminating the conveyor line.
